Spinach aphid disease is very common, how to control spinach insect aphidosis?

Prevention and control should be based on agricultural prevention and control, strengthen cultivation management, take the cultivation of insect-free seedlings as the main measure, rationally use chemical pesticides, and actively carry out physical control. When aphids are found.

When there is harm, prevention is the priority, disease-resistant varieties are selected, and harvest in time. Prevention first, scientific and safe medication! Imidacloprid.

Spraying is an effective way to prevent spinach aphids. Select varieties resistant to diseases and pests, and carry out physical and chemical control in a timely manner. Spinach aphids can be treated with imidacloprid, enylclotham, dried aphids, and dinotefuran.

and so on. Aphids are a common vegetable disease, and spinach is not immune. Controlling spinach aphids is a headache.

So how to prevent spinach aphids? Let's take a look at how to control spinach aphids.

North China. It occurs more than 10 generations per year in the Yangtze River basin.

20-30 generations occur per year. In temperature conditions where aphids reproduce, it can occur in both the north and south throughout the year. Aphids have a strong tendency to yellow, avoid silver-gray. Adults and nymphs.

It mainly sucks the sap on the back of the leaves and young stems and secretes honeydew. Causes the leaves to curl and grow to stagnation. Prevention and control should be based on agricultural prevention and control, strengthen cultivation management, take the cultivation of insect-free seedlings as the main measure, rationally use chemical pesticides, and actively carry out physical control.

Spinach is an indispensable vegetable in life. Spinach aphid is a pest with a high incidence and long damage period in the growth process of spinach, which seriously affects the planting efficiency of farmers. Aphids feed on host sap, causing the leaves to curl and grow slowly or stagnate, resulting in poor plant growth.

In severe cases, the entire plant will wilt and die. At the same time, it can also spread a variety of viral diseases, seriously affecting the normal growth of plants, resulting in a decrease in quality and yield. Spinach is a common vegetable in our life, with good taste and high nutritional value, and is deeply loved by consumers.

In the process of spinach growth, aphids are a pest with a high incidence and a long time of damage, which seriously affects farmers' income.

They are constantly sucking the sap from the leaves with their stingers. After sucking, it loses water and wilts, eventually causing the leaves to curl up, slow or stagnant growth, and spinach to grow poorly. During its outbreak, a large number of aphids gather on the leaves, which will suck up the entire leaf in a short period of time, causing the entire plant to wilt and die.

At the same time, it is also a spreader of various diseases such as viral diseases, which seriously affects plant growth, affects the yield in the later stage, and even causes no harvest. It has a strong tendency to yellow, and a silvery gray avoidance type. Adults and nymphs gather on leaves and young stems to absorb sap.

Honeydew can also cause leaf curling, growth stagnation, and disease transmission.

Pesticides. Because after my spinach is sprayed with pesticides, there are no aphids, so pesticides should be used to control it.

Pesticides should be used to prevent and control them, because this insect is very afraid of pesticides, so it will die after a beat.

Spinach planting selection of disease-resistant varieties, found that the diseased plant in time to pull out, concentrated burning, scientific watering and fertilization, rainy season drainage measures, appropriate amount of phosphorus, potassium fertilizer, promote the growth of the plant robust, aphids with dimethoate spray, leaf miner fly with phosphine milk hand digging oil, trichlorfon powder spray, downy mildew with redomir, chlorothalonil spray, anthrax with a potato Xunji tobuzin, carbendazim spray control.

A common disease in spinach cultivation.

1. Spinach downy mildew:Harm the growth of leaves, the leaves just appear light yellow irregular small spots, and then the lesions are connected to each other, if the situation is serious, the leaves are yellow, the diseased leaves rot in the rainy season, and there is a gray-purple mold layer on the back of the diseased leaves.

2. Spinach white spot disease:Harm the growth of leaves, the lower leaves are the first to start the disease, the edge of the lesion is obvious, if the air humidity is large, the hair will grow on it, it is easy to develop the disease under warm and humid conditions, low-lying terrain, poor ventilation, poor management, and serious disease.

3. Spinach wilt:Spinach often appears wilt at the stage of adult plants, the old leaves darken and lose their luster, the mesophyll turns yellow, the roots gradually turn brown and die, high temperature and humidity are conducive to the disease, the soil temperature is about 30 degrees, the soil is moist, the fertilizer is not fully decomposed, and the underground pests and nematodes are prone to disease.

4. Spinach anthracnose:The main celery should harm the growth of leaves and stems, and the leaves appear pale yellow stains, and then gradually expand into gray-brown lesions, with small black spots, and the disease is serious under the conditions of rain, low-lying terrain, poor drainage, poor ventilation and high humidity.

Cultivated spinach is the main pest.

The main insect pest of spinach is leaf miner, which will eat the mesophyll, leaving only the epidermis and forming a wide tunnel, which makes spinach lose its commodity value and suffer serious losses.

Spinach pest control.

Select disease-resistant varieties, find that the diseased plants are pulled out in time, burned in a centralized manner, scientifically watered and fertilized, do a good job of drainage measures in the rainy season, apply phosphorus and potassium fertilizers in an appropriate amount to promote the growth of plants, aphids with dimethoate, anti-aphid spray, leaf miner flies with octathion emulsifiable concentrate, trichlorfon powder spray, downy mildew with redomir, chlorothalonil spray, anthrax with methyl tobuzin, carbendazim spray control.

Hello, how to cure spinach with worms.

Hello, your question teacher will help you inquire about the following thoughts: spinach has insects treated like this: you can use 70% thiamethoxam burning water bending Qi dispersible granules 3000 times, 10% dime dipyridoxam water dispersible granules 1500 times, 20% acetamiprid 1000 times, 30% enylene pymetrozine 2000 times, cyhalothrin 800 times, 70% imidacloprid water dispersible granules 6000 times, any 1 2 kinds of spray control.

I hope the teacher's reply can help you I wish you a happy life Thank you!

Summary. Dear, I'm glad to answer for you, spinach has insect methods as follows: The main bings of spinach are downy mildew bing, cataplexy bing, root rot bing bing and white leaf spot bing; The main insect pests are aphids, leaf miners, and spodoptera exigua.
